Question

What will be the product of additive inverse of $\frac{3}{7}$ and multiplicative inverse of $\frac{9}{14}$?

• A. 2/3
• B. -2/3
• C. 27/98
• D. None of these

Answer 1

The correct option is B -2/3

Additive inverse of $\frac{3}{7}$ =$-\frac{3}{7}$
Multiplicative inverse of $\frac{9}{14}$ = $\frac{14}{9}$
Product $=\frac{14}{9}\times -\frac{3}{7}=-\frac{2}{3}$
